Sia Soliola learning from 'Leipana' in NRL

He's the oldest player in Canberra's NRL squad to face Parramatta this weekend but Sia Soliola is still learning thanks to the lethal 'Leipana' right-edge combination.

The 30-year-old will replace Elliott Whitehead at second row in Saturday's match at GIO Stadium after the English international accepted a one-match ban for tripping.

On the right for the Raiders, centre Joey Leilua and winger Jordan Rapana are among the competition's most dynamic attacking threats while five-eighth Blake Austin has started the season in strong form.
